CONCRETE RAILWAY-TIE.I

SPECIFICATION forming part of Letters Patent No. 794,109, dated July 4, 1905.

Y Application iled November 3, 1904:. Serial No. 231,228.

To (all whom, if may concern:

Be it known that I, GEORGE S. MILLER, a

citizen of the United States, and a resident of Burlington, in the county of Chittenden and State of Vermont, have invented a new and usefulImprovement in Concrete Rail way-Ties, of which the following is a full, clear, and exact description.

The purpose of the invention is to provide a simple, durable, and'economic form of concrete railway tie in which the devices for seating and securing the rails consist in box structures having chambers to receive spikes and means for removably holding the spikes in said chambers in lirm clamping engagement at their heads with the iianges of the rails, it being possible to expeditiously and conveniently replace any damaged spike without disturbing the rails or an adjacent spike.

Another purpose of the invention is to provide means for connecting opposing box structures in a tie, which means also serve to materially strengthen the tie in a longitudinal and transverse direction. l

Theinvention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a longitudinal vertical section through the tie, illustrating the rail-receiving devices in end View and the rails in crosssection. Fig. 2 is a partial longitudinal section through a tie, drawn on an enlarged scale,

. and a vertical longitudinal section through a rail seating or retaining device and a crosssection through the rail; and Fig. 3 is a transverse vertical section, also upon an enlarged scale, which section is taken substantially on the line 3 3 of Fig. 1, showing the inner side of a rail seating or retaining device in side elevation.

A represents the receiving or seating devices for the rails O, the said devices being adapted to be contained in the tieB, which tie is made of concrete of any desired nature and is molded or blocked to the usual shape or to any necessary shape. The body portion of each receiving or retaining device A consists of two socket members 10 and 11,arranged at suitable distances apart, and each socket member 10 and 11 is provided with a chamber 12, extending through from end to end, the said chamber 12 being polygonal in crosssection, usually square or rectangular, such being likewise the exterior formation of the said socket members, as is clearly shown in the drawings. The socket members 10 and 11 of each receiving or seating device are connected by a bottom or base section 13, which is horizontally disposed, and the said bottom 13 is of suficient width to extend beyond the side faces of the said socket members 10 and 11, as best shown in Fig. 3.

At what may be termed the end portion of the projecting section of the bottom member 13, which in practice is nearest the end of a tie, upwardly-extending ears 14 are produced, (shown in Figs. 1 and 3,) and said ears are preferably integral with the socket members 10. These ears 14 are provided with apertures therein, and the side faces of the ears 14 are in direction of the end portions of the tie B when the receiving or seating devices A are fixed in the tie.

A locking-bolt 15 is passed loosely through the chamber 12 of each socket member 10 and 11, and said bolts are circular in cross-section and are of much less diameter than the diameter of the chambers of said socket members 10 and 11, as is clearly shown in Fig. 2. The said locking-bolts 15 at their upper ends extend well beyond the upper ends of the socket members 10 and 11, which ends are open, and the upper extremities of the locking-bolts 15 are threaded, as is shown at 16 in Fig. 2, vto receive lock-nuts 18, while at the other or lower end of each locking-bolt 15 ahead 17 is formed, usually rectangular or polygonal. In

fact, the heads 17 of the locking-bolts are given the same exterior shape as the exterior shape of the chambers 12 in the socket members l() and 11. The heads 17 of the locking-bolts 15 when said bolts are in posit-ion are located at the bottom portions of the socket members 1() and 11, the lower ends oi' said members being closed, as is illustrated in Fig'. 2, so that all working parts contained in the socket niembers are protected from the concrete or material ot` which the tie B is made.

The chambers of the socket members 10 and 11 are adapted to receive the body portions or' spikes 19, provided at their upper ends with heads 2O of the usual pattern adapted to engage with the flanges ofthe rails C. The body portions of the spikes 19 are of the same diameter throughout and are exteriorly formed to correspond to the interior formation ot' the chambers 12 in the socket members 10 and 11, which receive the body portions of the spikes. Each spike 19 is provided with a bore or aperture 21, extending through from end to end, as is shown in Fig. 2, and the apertures 21 in the spikes are of slightly greater diameter than the diameter of the body portions ol the locking-bolts 15. The locking-bolts 15 are held in upright positions in the socket members 'IO and 11 by producing' apertures in the heads 17 of the bolts and passing stay-rods 22 through the said apertures, which stay-rods extend out through openings in the bottom of the socket members 10 and 11 and when the tie is complete extend from side to side of the tie, or practically so, as is illustrated in Fig. 3.

D represents tie-rods, two o'tl which rods are employed in connection with each tie B. These tie-rods D are adapted to connect opposing receiving or seating devices A and serve to keep them from possibly creeping when set in the tie. strengthen the tie at the place between thereceiving' or seating devices, as shown best in Fig. 1. rlhese tie -rods are provided with threaded end portions 23, and said threaded end portions 23 are passed through apertures in the ears 14 on the body portions of the rail seating or receiving' devices. The said tierods are then held in position by means of suitable nuts 24, screwed on the extremities ot' the rods to an engagement with the outer faces of the said ears 14, as shown in Fig. 3.

The material of the tie B is molded around the devices A, their stay-rods and tie-rods, except the upper ends of the socket members l() and 11, which are iiush with the upper face of the tie. The bottom faces of the rails C at their i'langes are made to rest upon the inner upper surfaces of the socket members 10 and 11. The spikes 19 are then passed down over the locking-bolts 15 until the heads 20 of the spikes engage with the upper taces of the flanges oi'I the rails. Then the nuts 18 are screwed upon the upper ends of the locking-bolts, and as these nuts are screwed down on the heads of the spikes they bind the said heads to a tirm engagement with the iianges of the rails, since the head portions of the Said tie-rods likewise serve to said locking-bolts are firmly anchored and cannot move Upward or downward.

It will be observed that whenever desired a new spike can be substituted for one unduly worn or damaged by simply removing the nuts 18, withdrawing the old spike, introducing a new one, and again screwing the nuts 18 to place.

Having' thus described my invention, Iclaim as new and desire to secure by Letters Patent-- 1. In concrete railway-ties, a rail receiving or seating device, consisting of chambered body members, locking members held within the chambers et' the body members, and spikes fitted to the chambers of the body members and held in position by the locking members.

2. In concrete railway-ties, a rail receiving or seating device, consisting of a body member having a polygonal chamber extending through from end to end, a longitudinallyapertured spike litted to the chamber of the body member, a locking member for the spike passed through this aperture, and means for holding the locking member stationary with respect to the body member.

3. In concrete railway-ties, a socket member open at the top and closed at the bottom, having' a polygonal interior chamber, and a locking-bolt passed loosely through the chamber of the socket member, having an enlargement at one end for engagement with the closed end of the socket member, the other end of the said locking-bolt being threaded and carried beyond the open end of the socket melmber, and means for anchoring the said bo t.

4. In concrete railway-ties, an externallypolygonal spike provided with alongitudinal aperture extending' through from end to end.

5. In concrete railway-ties, an externallypolyg'onal spike provided with a tubular aperture extending through from end to end, a socket member chambered to receive the spike, a locking device passed through the aperture in the said spike, and means for holding the locking device stationary relative to the socket member.
